[Ursula]

The method for checking the engine oil level in a car is: 1. Park the vehicle on a level surface and turn off the engine; 2. Pull the hood release lever; 3. Open the hood and use the secondary latch to prop it up; 4. Locate the yellow or orange dipstick in the engine compartment; 5. Pull out the dipstick and wipe off any residual oil with a towel; 6. Reinsert the dipstick back into its original position; 7. After pulling out the dipstick again, observe it vertically or at a 45-degree angle. The oil level should be between the min and max marks to meet the requirements. The function of engine oil is to lubricate the friction surfaces of various components inside the engine, reducing friction and wear on the parts.
